This invention relates to dividing strips for cementitious fioors and the means for anchoring such strips in position prior to and during the laying of the fioor material, and the primary object is to provide unique, novel and eificient anchoring means that will combine with the floor strip in such fashion as to securely hold it against displacement after having been associated therewith at the point of installation without use of special tools or equipment.

One of the important aims of the invention is to provide a strong, yet relatively inexpensive anchoring means for floor strips, which includes a unitary structure having parts arranged so that the floor strip is engaged by a plurality of staggered elements to maintain the strip against tipping or lateral displacement, some of said elements having parts that engage the dividing strip in a way that will preclude lifting of the strip from the base after the same have been assembled.

Other objects of the invention include providing an anchor for dividing strips that may be stamped from a single piece of sheet metal; have an upstanding wall on a base wall that is slit and angled outwardly to afford strip-engaging members which permit easily associating strip and anchor, yet will snugly engage the sides of the strip when the same is disposed in the working position; and have an upstanding ear formed on the base plate of the anchor to hold the dividing strip in place against the edges of the upstanding wall formed by the slitting thereof, and which engage opposite sides of the said strip.

Since an anchor embodying the invention contemplated may assume a large number of specific structural forms, the objects fulfilled by the embodiment of these forms in all strip anchors will become apparent during the following specification, referring to the accompanying drawings, wherein exemplifications of many forms are illustrated, and wherein:

Fig. 16 is a perspective view of a composite anchor embodying the invention and made to properly support dividing strips at their point of intersection in the pattern.

Basically, the anchor per se in every instance comprises a base plate 20, which has means for securing the same in position upon one of two distinct types of supports. Some base plates 20 include both types of securing means and one may be dispensed with if necessary. Where the anchor is used in connection with a concrete support 22, the securing means may be downturned lugs M which project into a cement pad or pillow 26 that is supplied by the workmen and placed upon concrete 22 as the location of the anchors is determined.

The function of lugs 24 is clearly illustrated in Fig. 1 and reference to Fig. 9 will teach the manner in which nails 28 pass through apertures 30 formed in base plate 20 for the purpose of attaching the anchor to a wooden floor 32. In all instances the dividing strip is intended to present a longitudinal edge 34 at the upper surface 36 of the floor, which has a cementitious finishing material 38, known to the trade as terrazzo. The thickness of this finishing material is substantially the same as the width of each of the several types of dividing strips and since the dividing strips per se present different laterally extending structures for the purpose of forming transverse shoulders, the specific anchor for each type of strip is altered accordingly.

the anchor and In all instances, however, the anchor has an upstanding wall 40 slit or slotted intermediate its ends to present an edge 42 and an edge 44. The anchor is further slit longitudinally along the line of connection between wall 40 and base plate 26 so that a wing portion 46 may be created by bending outwardly that part of wall 48 adjacent the first mentioned slit or slot which forms edges 42 and 44.

In bending out wing 46, edges 42 and 44 are drawn apart and a relatively wide gate or distance between these edges 42 and 44 is provided which permits insertion of the respective dividing strip in all instances. Wall 46 i preferably created along one edge of base plate 20, and this wall, together with edges 42 and 44 should extend vertically perpendicularly to base plate 20 so that when the respective dividing strip is inserted, it will likewise be held in such relation to plate 28. Observation of the drawings teaches that edges 42 and 44 are not directly opposed and to fulfill one of the broader objects of this invention, there is formed on each anchor and from the base plate 28 thereof, an upstanding ear 48 that may be struck from or otherwise integrally created, upon plate 26. This ear 48 is, in all instances, intermediate wall 40 along one longitudinal edge of plate 20 and the other edge of said plate. This ear 48 engages the same side of the dividing strip as does edge 42 on wing 46 and, manifestly, edge 44 engages the opposite side of the respective dividing strip and there is presented elements in staggered relation that engage sides of the strip, with alternate elements engaging opposite sides of the strip. Not only will the structure defined to this point allow quick and easy insertion of the respective dividing strip, but it will be secured against lateral displacement and held substantially perpendicular to plate 26.

Because of the hereinbefo-re mentioned variation in the laterally extending shoulder-forming portions on the various types of strips, the stripengaging edges 42 and 44, and in some instances ear 48, must have special shoulder-engaging parts created thereon. In the instance shown in Figs. 1, 2 and 3, the dividing strip has a longitudinally formed embossment 56 that presents a transverse shoulder on each side of the strip.

Edge 42, therefore, has a projection 52 that extends into embossment 58 and edge 44 has a notch 54 to which the embossment extends. Ear 48 has a projection 56 which also extends into embossment 50 and these overhanging parts will obviously preclude lifting of the dividing strip from its anchor.

In Fig. 4, projection and notch 52 and 54 respectively is present to enter and receive respectively, embossment 50, but ear 48 is of diiferent form and without an overhanging part.

In Figs. 5, 6 and '7, the dividing strip has outwardly punched anchoring elements 58 that extend laterally to one side of the strip. A notch 68 is formed inwardly from edge 44 to receive one of these elements as the strip is moved longitudinally between edges 42 and 44 when the anchor is being positioned. The shoulder 62 formed by punching elements 58 from the strip affords a transverse surface over which projection 64 on car 48 might extend. Obviously, no lifting of the dividing strip can take place after the parts are associated as described and illustrated in these three last mentioned figures.

In Figs. 8 and 9 the dividing strip is similar to that illustrated in Figs. 1 to 4 inclusive and has the same embossment 50 to engage projection 52 and notch 54 as before set down. In this form, however, ear 48 has its wider surface facing the side of the dividing strip and its projection 66 is merely a transverse corrugation that extends into embossment 50.

In Fig. 10 the form of dividing strip is that having struck-out lugs 68, one of which extends to each side respectively of the dividing strip. Notches I0 and I2, formed inwardly from edges 42 and 44 respectively of wall 46, receive the laterally extending lugs 68, as shown. Ear 48 engages one side of the dividing strip, but no overhanging parts are present with regard to the dividing strip and this form of ear. It may be forced against the side of the dividing strip so as to properly function as one of the staggered elements.

The type of dividing strip illustrated in Figs. 11 and 12 is that having laterally extending shoulders 14 continuously along each side thereof and one of these shoulders is engaged by an edge 16 formed by notching wall 40 inwardly from edge 44 and the opposite shoulder 14 is engaged by the lower edge of wing 46, which in this instance is cut away along the lower portion to present such an edge 18. Ear 48 has a projection that overhangs one shoulder 74 and the broad object of the invention are again met by this specific structure as regards both strip and anchor.

In Fig. 13 the strip has double corrugations 80 and 82 extending to opposite sides of the strip and the first mentioned corrugation 8D enters notch 84 formed in edge 44 of wall 48. Projection 86 formed on ear 48 enters this corrugation 80 and a notch 88 formed in edge 42 of wing 46 receives corrugation 82.

' In Fig. 14, shoulders 90 and 92 are engaged respectively by lower edge 94 of wing 46, curled portion 96 of ear 48; and edge 98 formed by notching wing 46 at edge 42.

In the form shown in Fig. 15, there are laterally extending shoulders formed on each side of the dividing strip. Shoulders I 08 and I02 are engaged respectively by edge I04 and edge I06 and curled portion I08 of ear 48. It is notable in this instance that the shoulders on one side of the dividing strip only are engaged to preclude the lifting of the strip from the anchor.

Fig. 16 illustrates a form of composite anchor that is used at the zone of intersection of the dividing strips. These strips are of the form shown in Figs. 1 to 4 inclusive and 8 and 9, and the anchor per se is merely a unitary structure wherein is embodied the base plates 20 that assume the form of a bottom H0 having upstanding walls H2 along each of three sides thereof. Each of these walls has the previously described wing H4 that has a projection H6 for entering the embossment 50 while notch H8 receives the said embossment. Ears I28, having projections I22, assume the same relation with respect to providing staggered engaging elements and when this form of anchor is used at the point of intersection of the strips, one strip passes completely therethrough, while the two strips forming the intersecting line of the pattern abut each side respectively of the continuous strip. The invention is completely embodied in this form and a rigid, effective, and completely satisfactory anchor is produced.

In making the various types of anchors illustrated and described, forming from sheet metal is contemplated. This metal may be slightly resilient, but since the invention is clearly exemplified in a large number of modified forms, it is obvious that it may be built into anchors having characteristics greatly removed from those specified.
